ALBIN IVARTH, OF STAPLETON, l\'E\V YORK.

MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 444,286, dated January 6, 1891.

Application filed October 2, 1890.

To aZZ whom it may concern.--

Be it known that I, ALBIN \VARTH, a citizen of the United States, residing at Stapleton, in the county of Richmond and State of New York, have invented new and useful Improvements in Mechanical Movements, of which the following is a specification.

This invention relates to certain improvements on a mechanical movement described in Letters Patent No. 172,803, granted to me January 25, 1876, which is intended particularly for el0th-cutting machines, but which is applicable to tools of diiferent kinds such, for instance, as polishing-tools.

The improvements which constitute the subject-matter of my present invention are pointed out in the following specification and claims and illustrated in the accompanying drawings, in which Figure 1 represents a plan or top view. Fig. 2 is a side view. Fig. 3 is a transverse section in the plane .90 a", Fig. 1. Fig. 4 is a transverse section in the plane y 3 Fig. l, on a larger scale than the previous figures. Fig. 5 is a horizontal section in the plane 00 00, Fig. 2. Fig. 6 is a vertical section in the plane z .2, Fig. 5. Fig. 7 is a plan or top view of a modification. Fig. 8 is a side elevation of the same. Fig. 9 is a transverse section in the plane at, Fig. 7. Fig. 10 is a transverse section in the plane y y, Fig. 7, on a larger scale than the previous figures.

In the drawings, the letter Adesignates a track which is composed of two bars a a, secured in any suitable manner at such an elevation from the ground that room is obtained beneath it for the table B and for the tool 0 and the mechanism for actuating the same, as hereinafter described.

On the track A is fitted the carriage D, which has four wheels (1 d 011 one side (see Fig. 2 and a single wheel (1 on the opposite side, (see Fig. 1,) the wheels (Z (Z being made to engage the bar a of the track, while the wheel (1 bears upon the bar a. The axles of the wheels d d have their bearings in the side plates d, and the axle of the wheel d has its bearings in the side plate C1 and these side plates are connected by transverse bars E F Serial No. 366,825. (No model.)

which 'it is prevented from turning in either direction beyond a certain limit.

On the lower part of the vertical arbor If is firmly secured a tray g, the object of which will be hereinafter explained, and below this tray is situated a cage I, which is firmly se-,

cured to the arbor H, and which, together with said arbor, forms a hanger, on the bottom plate of which are firmly secured two brackets h, Figs. 4, 5, and 6, which form the bearings for a roclcshaft 'i, and 011 this rock-shaft is secured a plate K, which forms the support for the balance-arm L. This balance-arm is provided with a slot Z, and it is secured on the plate K by screw-bolt 7. which extends through the slot Z, Figs. 5 and 6.

From the plate K extends a lug into the slot- Z, so that when the nut of the bolt 7; is re leased the balance-arm L can be moved in the direction of its length, while it is steadied by the lug 7t. From this description it will be seen thatthe balance-arm L can swing on the vertical arbor H in a horizontal plane in either direction as far as the stopf will permit, while itcan swing on the rocloshaft 'i in a vertical plane. The balance-arm carries the tool 0 on one side of its fulcrum, and on the other side of its fulcrum is placed the motor M, such as an clectromotor or a pneumatic motor, or any other motor suitable for the purpose, and which is adjusted on the balance-arm in such a position that it countcrbalances the weight of the tool. If an electromotor is used, the wires which form the connection with the generator of electricity are carried through a tube or guide N, which is attached to the carriage D, and from the bottom part of this tube they are carried to the tray 9 and through on opening in the side of this tray to the electromotor, so that they do not become twisted or entangled by the movements of the balance-arm. If a pneumatic motor is used, the tube which conveys the compressed air to the motor will occupy the place of the wires.

In the balancdarm is mounted a shal't lit, to which motion is imparted by the motor M, and which is geared with the tool t.

In order to be able to use two tools 0" 0 side by side, I arrange two single tracks A A, as shown in Figs. 7 to 10, inclusive. In this case the carriages I)" D are consi ructed each with four wheels,whieh engage the tracks A A as shown in Figs. 8 and 9, and from each carriage rises a standard 0 t), which carries two wheels 0 o o 0 to engage rails 19 p, which are fixed overhead. By these means the carriages are retained in an upright position, and they can be run close together. The balance-arms L ID are connected to the carriages D D in the same manner in which the balance-arm It is connected to the carriage D, Fig-s1 to 6, and each of the balancearms If L carries its own tool and its own motor. From this description it will be seen that when the balance-arm L is mounted. on a hanger depending from the carriage I) the tool attached to the balance-arm can be swung clear around without obstruction, and free access can be had to the table I; and to the work supported by said table from both sides.

The balancearm is secured in the hanger formed by the cage I and arbor l-l, so that it can be adjusted in the direction of its length and that it can be broughtin the position in,

which the motor M forms a counter balance for the tool C, and by adjusting the arbor It up and down by means of the nut c the position of the hanger and of the balance-arm can be regulated so that the tool or its foot-plate will bear flat upon the table. \Vhen the nut c is loosened, the balance-arm is free to more in the direction of its length.

The table 13 is provided with wheels which rest upon rails, and a rope serves to move the table upon the rails.

I do not herein claim what is described and claimed in my applications, Serial Nos. 363,983 and 363,884, filed September at, 1890.

hat I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the track A and the carriage D, of a hanger depending from the carriage, a balance-arm Ii, mounted in the hanger and free to swing both in a horizontal and in a vertical plane, a tool attached to the lntlance-arm, and a motor M, carried by the balance-arm and geared with the tool, substantially as described.

2. The combination, with the track A and the carriage I), of a hanger depending from the carriage, a balance-arm mounted in the hanger and adjustable in the direction of its length, said balance-arm being free to swing both in a horizontal and in a vertical plane, atool attached to the balance-arn't on one side of its fulcrum, and a motor attached to said balancearm on the opposite side of its lulcrnm and geared with the tool, substantially as described.

The combination, with the track A and the carriage D, of a hanger depending from and free to swivel in the carriage, a guide N, secured to the carriage, a tray g, secured to the hanger, a balance-arm supported by and swinging in a horizontal plane with the hanger and adapted also to swing thereon in a vertical plane,a tool 0, attached to the balance-arm, and a motor M, carried by the balance-arm and geared with the tool, substantially as described.

4. The combination, with the hanger Ii I, of a balance-arm mounted in the hanger and tree to swing both in a horizontal and in a vertical plane, a tool secured to the balance-arm, and a motor carried by the balan cearn1 and geared with the tool, substantially as described.

5. The combination, with the hanger II I, of a balancearm mounted in the hanger, said lmlancearm being free to move in the direction of its length and to swing both in a horizontal and in a vertical plane, a tool secured to the balance arm, and a motor carried by the balance-arm and geared with the tool, substantially as described.

In testimon y whereof I have hereunto set my hand in the presence of two subscribing witnesses.

A'LUIX WARTLI.
